I was thinking about what type of perch to build while I was planning my new coop today. As a former dog groomer, I always think about overgrown claws. I hear that OEGB like to perch on their person's arm and/or shoulder. I thought about building a perch equipped with a fine sand paper strip at the bottom where the claws would catch onto the perch. It would be useful in running down those talons. I've seen entire perches covered in sandpaper that parrot owners seemed to use often enough, but I would think that would be slightly uncomfy for the bird. Maybe I'm over thinking it but it's not a bad idea.
